Improved in carpet-fastener



UNITED STATES PATENT OFFICEI TROILUS H. TYNDALE, OF SPRINGFIELD, ILLINOIS.

IMPROVED IN CARPET-FASTENER.

Specification forming part of Letters Patent N o. 87,991, dated March 16, 1869.

To all lwhom it may concern:

Be it known that I, TROILUS H. TYNDALE, of Springfield, in the county of Sangamon and State of Illinois, have made certain new and usefulImprovementsin Carpet-Fasteners; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to certain devices for securing and retaining in position carpets, mattings, oil-cloths, and covers of similar nature.

The nature of said invention is in the peculiar construction of the spring-prongs for holding the carpet or matting, in the manner of its connection to the fastener-bar, and in such other features of construction as are hereinafter more fully described.

To enable those herein skilled to make and use my said improvement, I will now more fully describe the same, referring to the accompanying Figures l and 2 as front and side elevations, respectively, showing the parts as in adjustment; to Figs. 3 and 4 as plan 'and elevation, respectively, of a socket for corners of a room; to Fig. 5 asa longitudinal section, and Fig. 6 as a transverse section, showing the method of attaching the barbed springs used in this improvement to the fastener-bar.

In the ordinary application of my said devices to holding and securing carpets or mattings in apartments, I secure the socket A by ordinary screws a to the wash-board or furrin g at a small distance above the floor, so that the v outer edge of the carpet may pass closely to the wash-board edge, and thus leave less room for entrance of dust and rubbish. For this purpose the lower surface of the socket A will be rounded, as indicated in Figs. 2 and 3. The said socket will be formed of brass, malleable iron, or similar material, and have a mortise, al, on one side, and a slot, a2, on the other side, into which the fastener-bar B will engage. Said bar will be usually a metallic rod of convenient length, the ends whereof will be formed as tenons b, to fit the mortise and slot of the socket A. The tenon iitting into the mortise al may be slightly rounded, so that the bar B may be readily inserted in the socket on one efectually end, and-the tenon at the other end may then be readily dropped down into the slot a2 of the socket at this end. A proper set-screw, a3, or a simple bolt passing through a hole in the tenen, will retain this end of the bar, and in this wise the bar is adjusted in proper position. At corners of a room the socket A will be formed as indicated in Figs. 3 and 4.

On the under side ofthe fastener-bar B, I arrange the springs C, the springs being recessed in the bar, and secured, by screws or rivets c, thereto. Said springs may be of any usual material-such as brass or steeland of any desired form, and the same will be arranged with barbs or pointed prongs c at the outer ends. It is plain that when the carpet or matting is drawn under the fastener-bar B, and this bar then forced down, the barbs c will penetrate the carpet or matting, and thus hold the same. By making the said barbs c of suflicient length, they will also penetrate into the flooring, and thus give additional support.

Moreover, the springs U being recessed in the bar B, the projecting sides of this bar will prevent the springs from being withdrawn laterally, and thus, in the event of strain by wear or shrinkage, the said parts will afford a sufticient resistance.

Ifit be objectionable to penetrate the carpet by the barbs c', then the lower surface of the spring C will be simply roughened or ridged, so as to take hold upon the carpet-sur face.

Having thus fully described my invention, what I claim is- 1. The socket A, its mortise al, and slot a2, in combination with the fastener-bar B and screw a3, substantially as and for the purpose set forth.

2. The bar B, arranged' with recesses, and combined with the springs C, substantially as and for the purpose set forth.

In witness of said invention I have hereunto set my hand.

TROILUS H. TYNDALE.
